4th, I have those same mags, got them from Cheaper than dirt. Got two of them, each worked great for a good while, couple months, probably a few hundred rounds through each mag, but then they started to do that exact same thing as yours did. I have a chip mcormick mag, and havent had any problems with it. but those little colt (knockoffs?) were a dissapointment.

Get some wolf springs for them. If you leave them loaded even with a few out they take a set and get week. I have some 8 rnd chip and some 7 rnd springfields and they use to work great but some of them took a set. So other than normal spring fatigue the bodys have done great...

Ah hell. I already heaved them in the canal. Friggen junk.
You know they did not have the little horse on them. Good thinking.
Probably built by commies, fake commie colts.
Even that pistol is a Chinese commie .45.
Bought the .45 Norinco, pre ban. Shoots pretty darn good rite out of the box brand new for the $260 I paid for it years ago.
Guys. Read through the article "link" Sniper put up. Kinda long but very informative on mags, feed ramps etc..

Yes. I just ordered Chip McCormick mags from Cheaper than dirt.
Kind of a lessons learned for me on mags. Glad I went with my buddy too the range and got too find out they were not working.
I just kind of took the mags for granted. But now I will check them more often. In all my semis.

15 years ago or so when clinton was cutting up the 45's there were two styles of surplus USGI mags out there super cheap. The newer ones had a larger stamp for the # of the magazine and a better finish along with slightly larger holes in the side of the mag. The older ones had the number stamped smaller, the finish was rough and the holes in the side of the mags were smaller. The newer mags sucked. I had no problems with the older ones. I also have quite a few 8rnd chip mccormick mags and the shooting star mags. Those are from about 15 years old also and they look like they were made by the same people. They also have been flawless in function over the years.
